I recently restored a laptop, a custom SONY VPCF1390X, using the built-in recovery partition. Everything went about as well as I expected, but I noticed that download speeds were much lower than what I usually get. I've checked my network speed on the laptop and on other PCs I own and it seems to be the only one affected, what takes less than a minute to download on my desktop takes hours on this laptop, And there were no network problems before I restored it.
My first thought was to download the drivers, which is actually what I was trying to do when I noticed speed discrepancy. So I checked Sony's page and my drivers were up-to-date. I downloaded and installed them anyway, in hopes that it may fix it, but it did nothing.
Since then I've changed ISPs and went from 5mbps (which was closer to 3mbps) to 40-41mbps. But still had the same awful performance, it didn't even scale with the upgrade, stayed basically the same. It does seem to be sporadic, though very frequent, enough that the slow is the norm, with very small bursts of speed every once in a while.
I've even taken the computer to work and used the network there with no effect. My original idea was to restore this computer back to a fresh state so that I could use it in my job, but as a programmer, I often need to download large files and use the internet to research solutions, so I'm stuck with my previous laptop until I can fix this problem.
PS: Problem exists when connected either by cable or wireless.
Here is a post with the laptop's specifications:

EDIT:
Router model is a Cisco DPC3925. But I had a different router (and ISP) when this all started, and I also have the problem while using other connections. The adapter I usually use is the "Atheros AR9287 Wireless Network Adapter" since I mostly connect through wi-fi. I have tried the Marvell Yukon LAN port, but it was no different than wireless, so I'm pretty sure it's not a hardware issue.
Could anyone recommend a good Linux build that I may test a theory? Maybe something went wrong in the installation, and Windows is the problem. I'm thinking I can boot into Linux on a Stick and do a speedtest from it maybe it will prove me right or at least point back at the hardware issue...
After you do this recovery, did you wonder when this recovery partiton was made, and how many updates came after it? The title uses the words "system restore" which on windows systems is to retract small changes and could cause an issue or change things without changing others (mixed up) , if it is only a "Recovery" that is different. Because there are all kinds of servers out there with varying speed at times, did you do a "speed Test" which varies too but is one test. Then something to use to check your "tcp" parameters is one thing? – Psycogeek – 2014-04-24T02:31:55.407
It's the recovery partition that the laptop comes with from Sony, not a System restore created by me. It restored the PC to how it came when I bought it. – Kross – 2014-04-24T09:53:12.683
I tested the speed using speedtest.net, and I get around half my bandwidth (15-20 mbps out of 40 mbps). However I also tested by downloading a 200mb file, and Firefox reports it as downloading at 2 mb/s and it continues to drop in speed the longer the download takes. Simple web browsing is bearable, but not fast by any means, and it often gets stuck loading a page, so I have to refresh. Ping seems to be similar to other PCs in the network. – Kross – 2014-04-24T09:58:56.343
FYI: 2MB/s is 16mpbs – horatio – 2014-04-26T17:22:32.723
Do you get the same issues when booting any Linux live distribution? – and31415 – 2014-04-27T10:09:55.370
They were much worse in Linux Mint... I wanted to try and find drivers for the network controller, but I couldn't find an option for it. – Kross – 2014-04-27T16:00:42.580
You should mask MAC addresses in future. I am doing that for you right now. – tumchaaditya – 2014-04-28T20:24:51.280
Is it slow too when you take that laptop to work and try there? On wlan and on lan? – rubo77 – 2014-04-29T18:10:50.213
Yes on both counts. I tried at work, at home and with a previous ISP. Also Wired and Wireless. – Kross – 2014-04-29T20:11:15.177
